Page 236 - Comparing that motion to the flow of a river, he propounded the theory that " a glacier is an imperfect fluid or a viscous body, which is urged down slopes of a certain inclination by the mutual pressure of its parts.
Page 265 - This locality is apparently on or about the south base of the west Lomond Hill, overlooking Loch Leven. Subjacent to the limestone, which is richly fossiliferous, is ochre interbedded with shale, according to Dr. M'Kelvie. This ochre abounds in globular masses of iron pyrites, known to the quarrymen as "fairy balls," from the size of a fist to that of a man's head.
Page 91 - In examining the history of mankind, as well as in examining the phenomena of the material world, when we cannot trace the process by which an event has been produced, it is often of importance to be able to show how it may have been produced by natural causes.
Page 367 - The Society meets on the First and Third Thursdays of each month, from November to May inclusive.
Page 184 - ... mind that what has life must possess more power than that which is inanimate : consequently, if there was a transfer of power by the ordinary laws of nature, it would pass from that which is alive into that which is not : that is, if it tended to an equalization, it would quit and not enter the body. But so far is this from being the case, that we find that the body receives an increase of power during sleep. There remains, therefore, but one inference to be drawn from this fact, namely, that...
Page 330 - Druinry, as ascertained by a bore put down, is 230 feet. For several miles to the east the depth is nearly as great. Consequently, if this hollow be an old river-bed, the ancient river that flowed in it must have entered the Clyde at a depth of more than 200 feet below the present sea-level ; and if so, then it follows that the rocky bed of the ancient Clyde must lie buried under more than 200 feet of surface deposits from Bowling downwards to the sea.
Page 301 - ... any hitherto described. These beds from the contained fossils appear to be Cretaceous. Everywhere the strata named form a characteristic accompaniment of the coal (especially this coarse conglomerate), and nearly everywhere it is underlain by one or more seams of coal cropping out at some point on the circuit named, though it may reasonably be supposed yet to be found on the opposite shores of British Columbia. Outcrops are seen on some of the coast-lying islands, &c. ; but it is only at Nanaimo...
Page 236 - ... to these great mountains, where he toiled with a devotion that told at last upon his physical frame. ' The lessons which he had laboriously learnt among the living ice-rivers of the Alps bore fruit when he came again to wander among the more mountainous regions of his own country. In the year 1840 Agassiz had made the startling announcement that the British Islands had once been deeply buried under a vast mantle of snow and ice, and that the traces of its seaward motion were yet fresh and clear...
